The Franciscan reformer Ubertino da Casale was the author of the Arbor vite crucifixe Jesu—sometimes translated as The Tree of the Crucified Life of Jesus. This work had a strong effect on later Franciscan rigorists and on some prelates and monarchs; figures who were influenced by it include Dante, Giovanni dalle Celle, Saint Catherine of Siena, Saint Bernardino, John Brug-man, and King Martin I of Aragon.
